摘要:深基坑支护是在工程实践探索中发展起来的,具有一定的地区性。以上海虹杨变电站项目基坑围护工程为例,研究上海地区深基坑项目通常采用的围护形式及工作内容,各组成内容中的具体工作内容及其对应的费用组成、造价指标,并分析组成内容在整个基坑围护造价中的比重。最后得出常规的估算方法并进行验证,对深大基坑围护工程的估算具有一定的参考意义。关键词:基坑支护;工程造价;围护工程;造价指标;估算Abstract:Deep foundation pit support which developed in project practice has empirical regionality. Taking foundation pit supporting project of Shanghai Hongyang transformer substation project as an example,the paper studies the usually adopted envelope form and work content of the deep excavation projects in Shanghai,the specific work of composition content and the corresponding cost composition and cost index,then analyzes the proportion of composition content in the foundation pit support cost. Finally,obtains the conventional estimation methods and verifies these methods,which have reference significance to the cost estimation of deep foundation pit support project.Keywords:foundation pit support;project cost;supporting project;cost index;estimation参考文献[1] 张召冉,陈华义,矫伟刚,等.井筒工程BPNN造价估算模型应用研究[J].建筑经济,2015(9):72-75.[2] 赵锡宏.大型超深基坑工程实践与理论[M].北京:人民交通出版社,2005.[3] 周远忠,刘新荣,余瑜.大型红粘土深基坑工程造价计算与控制分析[J].建筑经济,2014(6):55-58.[4] 张仕廉,陈珂.基于Uniformat Ⅱ的建设工程投资估算方法研究[J].建筑经济,2014(1):45-48.工程经济,2016(08):05-08
